When Jesus leaves the house, he calls Levi, the Jewish tax collector, to follow him. Levi prepares a big meal for Jesus which annoys the Pharisees and scribes.
The phrase "these things" refers to what happened in the previous verses. This signals a new event. (See: [[rc://en/ta/man/translate/writing-newevent]])
To "follow" someone was a term that means to become their disciple. AT: "Be my disciple" or "Come, follow me as your teacher" (See: [[rc://en/ta/man/translate/figs-idiom]])
